Productivity of legume-rhizobial complex under the influence of growth-stimulating microorganisms

The lack of a general transition to environmentally oriented (environmentally friendly) agriculture is primarily due to the fact that use of biologicals shows unstable effects. An impact of the introduced microorganisms on the native soil microbiota, in particular, on natural microbial-plant relations, remains little studied. The purpose of this work was to study the effect of growth-stimulating strains of Paenibacillus ehimensis IB 739, Pseudomonas koreensis IB-4 and Ps. chlororaphis IB-51 on the legume plant-an aboriginal microbial community ecosystem. Seeds of pea ( Pisum sativum L.) variety Chishminsky 95, white lupine ( Lupinus albus L.) variety Dega, chickpea ( Cicer arietinum L.) variety Zavolzhsky, alfalfa changeable ( Medicago ½ varia Martyn ) variety Galia, white melilot ( Melilotus albus Medik.) variety Chermasan were treated with liquid cultures of rhizosphere bacteria strains. Sterile tap water was the control, and well-known microbiological fertilizer Azotovit® based on Azotobacter chroococcum B-9029 strain was the standard...
